Ultimate Geometry Resource

GeometryGeometry is the branch of mathematics that deals with shapes, their size and their position in relation to space. Geometry principally originated as more practical knowledge, mainly due to its fundamental role in architecture. However, modern geometry has broadened so that it has become highly mathematical and is used in an innumerable amount of fields.

Best Online College has put together a collection of online resources, activities and more to be used as the go-to resource for teachers and parents alike so that their pupils can grasp and enjoy the geometry fundamentals.

Cool Geometry Facts:

  • The plural form of radius is radii (Funtrivia). The radius of circle or sphere is any straight line from its center to its perimeter.
  • Lewis Carroll, who wrote “Alice’s Adventures in Wonderland” was an Oxford mathematician, logician and photographer and incorporated many geometry-related references in his works (Online Math Learning).
  • In 1897, the Indiana General Assembly attempted to pass a bill to define pi as equal to 3.2 by law. The goal of this bill wasn’t driven by scientific triumph but more by greed. The end goal was to make all those who used ‘pi’ pay royalties for it’s use. Fortunately, the bill did not pass (Dialspace).
  • Euclid of Alexandria was known as the “Father of Geometry.” He lived in Alexandria around 300 BC. His “Elements” has been an influential work in mathematics. Euclid still remains a top influencer in the field of geometry (Encyclopedia Britannica).
  • Two oddly named mathematical theorems are related to geometry: the Ham Sandwich Theorem and the Hairy Ball Theorem (Dialspace).
